"The progression of students to third-level study from all 723 secondary schools in the Republic of Ireland was examined. Data was collected from 29 third-level institutions under Freedom of Information legislation. This data mainly originated in the State Examination Commission and Central Applications Office. Third-level institutions do not stand over its accuracy when used to compile league tables. Data on admissions to Northern Irish, English, Scottish and Welsh universities and equivalent institutions came from UCAS.
In most instances, the data records the school where a candidate sat the Leaving Certificate on their first attempt. A small number of third-level institutions supplied data for both repeat and first-attempt students. Some excluded schools of fewer than three entrants. In these instances to reduce the distortion we examined the numbers repeating at each school and made other statistical adjustments. We excluded all external candidates. We also exclude several institutions which specialise in repeat exams. This adjustment means that in some cases those progressing to university and third-level is overstated.
Rank: For schools where % at university is the same, % at thrid-level is used to determine their rank in the Parent Power league table.
% at university: The number of students from the school, divided by three, who registered in the academic years 2010-11, 2011-12 and 2012-13 with one of the seven universities in the Republic of Ireland, mainstream state run teacher training colleges , the Royal College of Surgeons in Ireland (RCSI), National College of Art & Design (NCAD), or Universities in Northern Ireland, England, Scotland or Wales. for an undergraduate degree-level, full-time course. The number of students who sat the Leaving Certificate – adjusted for repeat students — in that school in June 2010 is then divided into this to calculate the percentage for 2010/11. The same method is used to calculate the percentages for 2011/12 and 2012/13. Source Leaving Cert Sits - State Examinations Commission, Athlone.
% at third-level: The average number of students from the school who registered in academic year 2010-11, 2011-12 and 2012-13 with
(a)one of the nine universities in the island of Ireland, mainstream state run teacher training colleges , RCSI and NCAD or Universities in England, Scotland or Wales for an undegraduate degree level full time course.;
(b) any other state-funded third-level college such as an institute of technology or National College of Ireland for a degree or sub-degree course. Private third-level courses are excluded. The percentage is produced by the same method above.
